Coronavirus researchers led by Professor Rolf Hilgenfeld of the University of Luebeck and PD Dr. Albrecht von Brunn of the Ludwig-Maximilian Universitaet (LMU) in Munich have discovered how SARS viruses enhance the production of viral proteins in infected cells, so that many new copies of the virus can be generated.Continuar Leyendo

Children with weakened immune systems have not shown a higher risk of developing severe COVID-19 infection despite commonly displaying symptoms, a new study suggests. Highfield, April 22, 2021.-  a 16-week period which covered the first wave of the pandemic, researchers from Southampton carried out an observational study of nearly 1500Continuar Leyendo

A new study led by researchers at Johns Hopkins and the University of Pennsylvania uses computer modeling to suggest that eviction bans authorized during the COVID-19 pandemic reduced the infection rate and not only protected those who would have lost their housing but also entire communities from the spread ofContinuar Leyendo

It has been known for about a year that minks can become infected with SARS-CoV-2. The virus had been transmitted from humans to farmed mink and mutated in infected animals. Mutations were acquired in the spike protein, which is crucial for the entry of the virus into host cells andContinuar Leyendo

Some survivors of ebolavirus outbreaks make antibodies that can broadly neutralize these viruses — and now, scientists at Scripps Research have illuminated how these antibodies can disable the viruses so effectively. The insights may be helpful for developing effective therapies. Los Angeles, April 19, 2021.- Ebolavirus is a family ofContinuar Leyendo

La Jolla, April 17, 2021.- Scientists at Sanford Burnham Prebys have identified a set of human genes that fight SARS-CoV-2 infection, the virus that causes COVID-19. Knowing which genes help control viral infection can greatly assist researchers’ understanding of factors that affect disease severity and also suggest possible therapeutic options.Continuar Leyendo

Although antibodies induced by SARS-CoV-2 infection are largely protective, they do not completely protect against reinfection in young people, as evidenced through a longitudinal, prospective study of more than 3,000 young, healthy members of the US Marines Corps conducted by researchers at the Icahn School of Medicine at Mount SinaiContinuar Leyendo

Patients who have preexisting respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD) and live in areas with high levels of air pollution have a greater chance of hospitalization if they contract COVID-19, says a University of Cincinnati researcher. Cincinnati, April 15, 2021.-  Mendy, MD, PhD, assistant professorContinuar Leyendo

A new state-by-state analysis shows a statistical association between high adherence to mask wearing and reduced rates of COVID-19 in the U.S. Charlie Fischer and colleagues at the Boston University School of Public Health in Massachusetts present these findings in the open-access journal PLOS ONE on April 14. Boston, AprilContinuar Leyendo

A tiny protein of SARS-CoV-2, the coronavirus that gives rise to COVID-19, may have big implications for future treatments, according to a team of Penn State researchers. University Park, PA.- April 12, 2021.- Using a novel toolkit of approaches, the scientists uncovered the first full structure of the Nucleocapsid (N)Continuar Leyendo
